In 2017, the NotPetya ransomware attack hit computers at shipping firm AP Moller-Maersk, requiring the firm to reinstall 4,000 servers, 45,000 workstations, and 2,500 applications in less than two weeks, costing the firm between $250 million and $300 million.
A ransomware group targeted Norwegian Ship Services in November 2024. The threat actor practices multi-extortion tactics and hosts a TOR-based website where victims are listed along with any stolen data if a victim fails to comply with the ransom demands. Since Ship Services has been providing essential maritime services across a broad spectrum for decades, such an attack can disrupt their operations and have an impact on the organization's reputation.
These are not merely isolated examples. A study by NHL Stenden University in Leeuwarden, Netherlands, recorded all publicly known cybersecurity incidents between 2021 and 2023 in the Maritime Cyber Attack Database (MCAD), which were around 290 attacks across 54 countries and over 50 ships.
The Looming Cyberattack Threat
The increasing digitalization of the maritime industry has its echo in the increased vulnerability of the "Global Maritime Transportation System" (GMTS), which includes shipping companies, port operators, ship traffic controllers, and other transport-related entities. Given that 80% of global freight is transported by ship, and 59% of these vessels are over 20 years old, cyberattacks can cause substantial collateral damage. The same digital currents that propel the industry forward can also create a dangerous "digital wake," threatening to capsize operations, compromise data, and leave the industry vulnerable to new and evolving threats. Given that the ship’s Operational Technology (OT) is generally of an earlier generation and less protected than the corporate technology, it becomes a fertile ground for threat actors to identify the ‘technology debt’ and target it for attacks. Beyond financial loss, these attacks could pose a direct threat to the safety of the crew, the integrity of the cargo, and the marine environment.
Systemic Fragility
The increasing dependence on technology introduces a dangerous element of systemic risk. The maritime industry has traditionally relied on redundant, analog systems for safety, but digital tools are quickly becoming the primary mode of operation. A failure in a single piece of technology, such as a GPS or a satellite communication link, could lead to a widespread GPS signal spoofing event or a major satellite outage that could cripple an entire fleet, leading to navigational chaos and potentially causing collisions or groundings. If a sensor fails to provide accurate readings on a ship’s engine performance or a port’s cargo levels, the resulting decisions could be based on flawed information, leading to catastrophic outcomes.
The Black Sea spoofing incident of 2017, where more than 20 vessels near Novorossiysk suddenly found their GPS systems showing false positions, is a textbook reminder of such systemic fragility. GPS, though indispensable, is inherently fragile: its signals are weak, easy to jam, and vulnerable to manipulation. For shipowners and operators, the lesson is clear: resilience doesn’t mean just adopting the latest technology, but ensuring redundancy and cross-verification across navigation systems. That means integrating radar, inertial navigation, AIS cross-checks, and even visual bearings as fallback layers. True resilience at sea comes from designing operations so that a single point of failure – like spoofed GPS – doesn’t compromise safety, compliance, or efficiency.
The Challenge of Data Privacy and Integrity
“Smarter” ships are data factories. Round-the-clock data collected from these vessels comprises vessel speed, routes, and fuel consumption, as well as crew biometric data and sensitive cargo manifests. A breach could expose proprietary business strategies, reveal the location of valuable cargo, or compromise the personal data of seafarers. Also, the integrity of this data is critical. Any manipulation of this data, either by an insider threat or an external hack, could lead to false operational reports, fraudulent transactions, or even falsified compliance data to circumvent regulations.
On January 7, 2023, Norwegian classification society DNV disclosed a ransomware attack targeting its ship management software. The breach directly affected around 70 customers and nearly 1,000 vessels – about 15% of its managed fleet. While vessel safety was reportedly not compromised, the scale of disruption underscores how deeply the maritime industry relies on interconnected digital platforms. With more operations from maintenance logs to compliance reporting moving into software ecosystems, cyberattacks no longer just threaten data but can ripple across global shipping networks. The DNV incident is a stark reminder that building resilience in maritime today isn’t only about physical assets or navigation systems; it must also extend to cyber defense, continuity planning, and digital redundancy.
Is Technology Really Disrupting the Workforce?
Automation can reduce human error, improve safety, and optimize emissions; it also gives rise to a new challenge: significant workforce impact. The maritime industry faces a crucial challenge in upskilling its workforce to handle new digital and automated systems while managing ethical and regulatory issues, such as who is liable in case of autonomous ship accidents. Secondly, what happens when a human operator, trained to take control, finds themselves in a situation where the automated system is malfunctioning? These are typical concerns that require extensive training and robust safety protocols.
It’s important to note that technology in shipping is not displacing human need: it’s the other way around. According to IMO reports, the maritime industry has a global pool of 1.89 million seafarers, yet a shortfall of 26,240 STCW-certified officers already exists, with an additional 89,510 officers needed by 2026. Beyond sheer numbers, the bigger challenge is capability: nearly 450,000 seafarers will need reskilling in green and digital competencies by 2030, a figure projected to rise to 800,000 by mid-2030. Far from reducing the importance of human expertise, the rise of digital and sustainable technologies in shipping makes skilled seafarers more essential than ever.
Digitalization Risks: Infrastructure and Monopolistic Trends
Digitization introduces both organizational and operational changes. Retrofitting older vessels with necessary sensors and communications equipment can be expensive and operationally disruptive.
Retrofitting costs in the maritime industry can vary widely depending on vessel type, age, and upgrade scope, but they typically range between $4 million and $6 million for significant enhancements. For example, cargo ship retrofits involving engine and propulsion upgrades ($3M), hull modifications ($0.5M), and digital automation ($1.5M) add up to about $5M, delivering a 20% fuel efficiency gain and compliance with emission standards: an ROI realized through reduced fuel bills, lower crew dependency, and avoided regulatory fines. Similarly, RoRo ship retrofits at around $4.6M improve loading efficiency by 30% and cut fuel use by 15%, while tanker retrofits at about $6M enhance structural safety and reduce operating costs by up to 20%.
The Broader Strategic and Regulatory Landscape
The technological transformation of the maritime industry is occurring within a complex geopolitical landscape. Nations and non-state actors are increasingly recognizing the strategic importance of global supply chains. This makes the shipping industry a target for economic warfare and disruption. A cyberattack on a major shipping company or port could be used to destabilize a rival nation's economy.
Building Maritime Risk Resilience
Increasing collaboration between ship owners, port authorities, and technology providers will also help anticipate, identify, and address risks in a rapidly changing landscape. Being proactive in recognizing technological vulnerabilities and agile in adopting countermeasures will define the successful maritime operators of tomorrow.
The digital revolution in maritime shipping is both a tremendous opportunity and a significant risk. Navigating this future demands a clear-eyed approach to technology’s dark side, balancing the drive for efficiency and growth with unwavering attention to safety, security, and resilience.
The industry must move beyond simply adopting new tech and embrace a proactive approach to risk management. This means investing in comprehensive cybersecurity defenses, building resilient and redundant systems, prioritizing data integrity, and thoughtfully integrating the human element into automated operations.
